The first MTB tires where Specialized's Sweet Spot Ply technology, combined with the casing angle, provides significantly more grip and control.

The new Specialized Grid Gravity Radial tires revolutionize the trail riding experience. By increasing the angle of the ply to the tested sweet spot, these tires achieve optimal grip, increasing traction and comfort – without compromising the lateral stiffness that riders need when cornering.
Unlike fine-tuning tire pressure, where compliance is quickly lost as pressure increases, or choosing a housing angle that is suboptimal for the desired ride feel, our radial housing design naturally creates the sweet spot: lower radial stiffness, preserved lateral stability, and a ride quality that makes technical trails noticeably smoother, faster, and more controlled.
